Definitions

the subject of the present invention is a pulley, in particular for a toothed belt, consisting of a pulley body and two flanges for guiding the belt.
Pulleys of this kind are used for driving rotating organs not only in the machine tool field but also in other fields, such as motor assemblies or control devices, etc.
the present invention aims to improve the manufacture of pulleys by various measures which can be combined and which provide improvements from various points of view.
a large number of pulleys of the type intended to cooperate with toothed belts, therefore having teeth on their periphery or of the type intended to cooperate with smooth belts, therefore having a smooth cylindrical surface on their periphery are provided with flanges intended to guide the belt, and these flanges consist of flat and thin rings engaged on cylindrical surfaces of the pulley body and fixed by crimping at three or four points around the periphery of the pulley, against a shoulder of the body.
the crown is bevelled on its internal face at its periphery.
the present invention therefore relates to a pulley, in particular for a toothed belt, consisting of a pulley body and two guide flanges of a belt, characterized in that the flanges are annular parts having an internal surface secured to the pulley body by radial tightening.
the pulley partially shown in Figures 1 and 2 consists of three parts: a pulley body 1 and two flanges 2 and 3.
the pulley body 1 has, at its periphery, teeth 4, intended to cooperate with the teeth of a toothed belt 5 shown in phantom in FIG. 1.
the flanges 2 and 3 are pieces in the shape of an attached crown, massive. These parts are machined with a cylindrical inner surface 6 whose diameter is determined with precision as a function of the dimensions of the grooves 7 and 8, formed in the top surfaces of the teeth 4. These grooves are located in the vicinity of the ends of the teeth, as is see in fig. 1. Their profile is rectangular. Their depth is adjusted so that the diameter of the bottom of the grooves Df is slightly larger than the machining diameter Di of the interior surfaces 6.
the top surface of the teeth 4 extends over a slight distance, after which the teeth 4 have conical surfaces that are slightly inclined and designated by 9 and 10.
the flanges 2 and 3 can be put in place by flushing on the conical surfaces 9 and 10 so that the elastic expansion allows them to engage in the grooves 7 and 8.
the flanges 2, 3 or 13 can also be put in place in the grooves 7, 8 or 14 by prior heating so that the diameter Di of the surfaces 6 is enlarged beyond the diameter of the top surfaces of the teeth 4 or 15 .
grooves 7 and 8 it is also possible to avoid grooves 7 and 8 and directly use portions of the top surfaces of the teeth, or the ends of the outer surface of the pulley body, in the case of a smooth pulley to seat the flanges by radial tightening, as described above.
